Which classification system is used to determine the severity of diverticulitis?

The Hinchey classification is specifically designed to assess the severity of diverticulitis by categorizing it into different stages based on clinical presentations and findings at surgery or imaging. This classification system helps in guiding treatment decisions and determining the appropriate level of surgical intervention based on the extent of the disease.

The stages of the Hinchey classification range from uncomplicated diverticulitis, classified as stage 1, to more severe forms such as peritonitis associated with perforation or abscess formation in later stages. This structured approach allows healthcare providers to evaluate the condition's severity effectively and aids in communication regarding the management plan.

Other classification systems listed focus on different medical conditions or areas. For instance, the Marchetti classification deals with testicular torsion, the Clavien-Dindo classification assesses surgical complications, and the Bismuth classification pertains to bile duct injuries, making them irrelevant to the specific assessment of diverticulitis.
